NAME

e - Unleash the power of e!

SYNOPSIS

Convert a data structure to json:

perl -Me -e 'say j { a => [ 1..3] }'

Convert a data structure to yaml:

perl -Me -e 'say yml { a => [ 1..3] }'

Pretty print a data structure:

perl -Me -e 'p { a => [ 1..3] }'

Data dump a data structure:

perl -Me -e 'd { a => [ 1..3] }'

Devel::Peek dump a data structure:

perl -Me -e 'dd { a => [ 1..3] }'

Add a trace marker:

perl -Me -e 'sub f1 { trace } sub f2 { f1 } f2'

Watch a reference for changes:

perl -Me -e 'my $v = {}; sub f1 { watch( $v ) } sub f2 { f1; $v->{a} = 1 } f2'

perl -Me -e '
    package A {
        use e;
        my %h = ( aaa => 111 );

        watch(\%h);

        sub f1 {
            $h{b} = 1;
        }

        sub f2 {
            f1();
            delete $h{aaa};
        }
    }

    A::f2();
'

Launch the Runtime::Debugger:

perl -Me -e 'repl'

Invoke the Tiny::Prof:

perl -Me -e 'prof'

DESCRIPTION

This module imports many features that make one-liners and script debugging much faster.

For performance, a simple 'use e' statement will import nearly no other libraries thereby making its startup impact quite low.

SUBROUTINES

monkey_patch

Insert subroutines into the symbol table.

Extracted from Mojo::Util for performance.

Perhaps can be updated based on the outcome of this issue: https://github.com/mojolicious/mojo/pull/2173

import

These keys will become sub names in the caller's namespace.
